Repair Invalid IMEI - Micromax Unite 2

One week after i brought my phone, I accidently formatted my device using sp flash tools and lost the IMEI/NVRAM. It has been a real pain for me to repair it because i was new to an mtk device. Finally figured out how to repair by doing many search. So I made this thread to share the working methods to help those people who are suffering from invalid IMEI :D

So let's start.

Always remember "Prevention is better than cure". If you are planning to flash a custom rom, First of all Backup your IMEI. Don't Trust that a custom ROM flash will not delete your IMEI number. because odds are it will. It's important to store your backup to external SD Card because while flashing some ROMs, it may also erase your internal memory.

So the best way to keep your IMEI number is to take my advise and make a backup.

DISCLAIMER: This guide is for educational purpose only. Changing IMEI number is illegal. Please don't misuse the guide.

Not fixed yet?? Make sure that you installed drivers properly. (Watch the below added video. )

Thanks to your tutorial. I was able to write my IMEI and now I can flash roms with ease. But, please also upload the CDC Drivers here cuz it was a pain in my ass to google and find the right ones for my old pc running on XP. But that sure is my job to do some research. BTW, I like the video and the way you keep it clean. A BIG THANKS TO YOU.

adding to my earlier comment the "NV Ram Database Files.rar" has Indonesian Database file which is not valid I suppose. So I searched for the file"BPLGUInfoCustomAppSrcP_MT6582_S00_MOLY_WR8_W1315_MD_WG_MP_V5_1_wg_n" gladly which was mentioned here. So please update that file too.
